Box Springs, Inc., makes two sizes of boxsprings: twin and double. The direct material for the twin is $30 per unit and S45 is used in direct labor, while the direct material for the double is $40 per unit, and the labor cost is $50 per unit. Box Springs estimates it will make 5,000 twins and 10,000 doubles in the next year. It estimates the overhead for each cost pool and cost driver activities as follows: Activity Cost Estimated Use per Use per Pools Driver Overhead Twin Double Framing Square feet of Pine $240,000 6,000 2,000 Padding Square Feet of Quilting 240,000 130,000 110,000 Filling Square feet of Filling 340,000 500,000 350,000 Labeling Number of Boxes 240,000 850,000 350,000 Inspection Number of Inspections 144,000 13,000 5,000 How much does each unit cost to manufacture? Do not round intermediate computations but round final answers for the fields below to the nearest whole number, Total cost per Unit Twin Double Direct Material 30 40 Direct Labor Cost 45 50 Overhead 779,000 x 425,000 X Total per Unit 155.BOX 42.5 X F Check My W The total cost per unit is determined by adding the per unit rates for direct material, direct labor cost, and overhead rate. The overhead rate involves the allocation of estimated overhead. More on that below. To determine the activity rate, divide the total of each driver (um of driver amounts for both products) into the estimated corresponding overhead amounts for each ost driver
